What animal missed the ark and no longer exists?

Answer 1

We can either answer this from The Bible, from speculation or, finally, from science and history.

1. From the Bible, we know God's intention because he clearly instructed Noah to take every kind of animal onto the Ark, and we know that Noah did exactly as told. The Bible says (Genesis 7:8-9) that two of every clean beast, two of every unclean beast and of everything that creepeth on the earth went into the Ark. There is no room in this passage for any animals not to do so.
   
2. Some have speculated that the unicorn missed the ark and no longer exists, although in fact it is an entirely mythical animal.
3. From a historical and scientific perspective, there never was a great flood that covered the entire world, causing the extinction of all animals that did not go onto the mythical Ark. If there was no biblical Flood, then there was no Ark and no animal that missed the Ark.

Answer 2

The dodo bird is known to have missed the ark and is now extinct. The dodo was a flightless bird that lived on the island of Mauritius and was hunted to extinction by humans and introduced predators.

Answer 3

Many species did not board the ark. Not because they "missed it," but because God's plan deliberately called for their extinction and He did not guide them there.
